Mr. Orban’s party, Fidesz, and the allied Christian Democratic People’s Party won 133 of the 199 seats in Parliamentary after a campaign that election observers called free but not entirely fair. They relied heavily on xenophobic rhetoric, and appeared to unfairly harness state resources, according to observers from the Organization for Security and Cooperation in Europe.

The majority is large enough to vote through changes to Hungary’s Constitution, a power Mr. Orban last held in 2015.

Since entering office for the second time in 2010, Mr. Orban has become a hero to the global far right for his nativist policies and for his efforts to mold Hungary into what he describes as an illiberal state.

In parallel, Mr. Orban has tightened his grip over Hungarian culture — targeting its artistic sphere, civil society and education system. He has sought to penalize rights groups, particularly those backed by the Hungarian-American philanthropist and financier George Soros. His narratives dominate state media and parts of the national curriculum, and his allies control most private media outlets and many universities and cultural institutions.
